175b262328 netifd: add udhcpc link check to dhcp shell handler script
Fixes the assumption the busybox udhcpc applet is always enabled; in case
the symbolic link check fails the DHCP shell handler script will exit and
as result the DHCP protocol handler will not be registered in netifd.

3bd2e195ec netifd: support DHCP sendopts as list options
Support config in the form of ....
	add_list sendopts=router:10.10.10.2
	add_list sendopts=nissrv:20.20.20.2
	add_list sendopts=0x7D:abba

This allows to configure sendopts having white spaces as option value

60e07ffec5 netifd: add defaultreqopts config option
By default udhcpc asks for a default list of options; the config option
defaultreqopts allows to tweak this behavior.
When set to 0 udhcpc will not ask for any options except for the options
specified in the reqopts config option.

012d20eebe netifd: update dhcp.script to handle dynamic routing
Certain DHCP servers push a gateway outside of the assigned interface subnet,
to support those situations, install a host route towards the gateway.

If Gateway and IP are served in same network, openwrt quagga cannot learn
routes (rip routes are not getting added, showing inactive) whereas
working fine when Gateway and IP are in different network.

abdf0dea3a netifd: always send DHCPv4 hostname
udhcpc doesn't send a hostname by default. Use the system hostname if
nothing else is specified, to always send a hostname.

It syncs the behaviour to odhcpc, which always sends a hostname.

89817614bb netifd: Request DHCP option 121 (classless route) by default
This option, defined by RFC3442, allows a DHCP server to send static
routes to a client.  But the client has to request this option
explicitely.

Static routes are useful when the gateway configured by DHCP cannot be
in the same subnet as the client.  This happens, for instance, when
using DHCP to hand out addresses in /32 subnets.

A new configuration option "classlessroute" is available, allowing
users to disable this feature (the option defaults to true).

Other DHCP clients already request this option by default (dhcpcd, for
instance, and possibly Windows).  If a DHCP server does not support
this option, it will simply ignore it.

f565e0598d netifd: Set source IP for DHCP static routes as well
Commit ce92f6650bd8a86db04c7a6cbb58e7fdb200a7e6 added source IP support
for DHCP default routes. As a side effect of this change the default route
could be present twice in netifd (once with source IP set and once with
source IP unset) if it was sent by the server in both the router and static
route options. Therefore add source IP support as well for static routes as this
case was not considered. Additional remove unused parameter type.
